valuation of Mineral Trioxide Aggregate and Calcium ydroxide Cement as Pulp-capping Agents in uman Teeth

( o ( a p bstract his study evaluated the histomorphologic response of uman dental pulps capped with mineral trioxide agregate (MTA) and Ca(OH)2 cement (CH). Pulp expoures were performed on the occlusal floor of 40 human ermanent premolars. After that, the pulp was capped ither with CH or MTA and restored with composite esin. After 30 and 60 days, teeth were extracted and rocessed for histologic exam and categorized in a istologic score system. The data were subjected to ruskal-Wallis and Conover tests ( .05). All groups erformed well in terms of hard tissue bridge formaion, inflammatory response, and other pulpal findings. owever, a lower response of CH30 was observed for he dentin bridge formation, when compared with TA30 and MTA60 groups. Although the pulp healing ith calcium hydroxide was slower than that of MTA, oth materials were successful for pulp capping in uman teeth. (J Endod 2008;34:1–6)
